204 If you think configure made a mistake, make sure you are using the latest
205 version from SVN. If the latest version fails, report the problem to the
206 ffmpeg-user@mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net.
208 if disabled logging

210 Rerun configure with logging enabled (do not use --disable-logging), and
211 include the log this produces with your report.
